jlv wrote:erode_limit <depth> <limit> <inner limit>This sets the erode limit at a specific depth. When the track is worn to the specified depth, the depth and inner depth will be multiplied by the limit and inner limit respectively. When between depths it will interpolate. Default is 1 1 at depth 0 and 0 0 at depth 1.

Will you help me understand this a little better please?First, is this the default settings as you have mentioned above?erode_limit 0.0 1.0 1.0erode_limit 1.0 0.0 0.0

First number is the depth? So, here we have a depth range of 0 and 1 foot? Does this have any relation to the erode_depth setting? It sounds like maybe between the 0 and 1, the first 1 foot of depth, it'll interpolate. After that it'll erode at a fixed value until it reaches erode_depth? Can you give me like a real working example of how changing each number would make the erode different? Please.

The first number tells it when to use that setting. If the track is worn 1 foot below the original height, it will use the line where <depth> is 1. The second and third numbers scale erode_depth and erode_inner_depth.

You have the default correct. That will gradually reduce erode_depth and erode_inner_depth to 0 as the track reaches 1 foot underground. Should be something like dirt that gets progressively harder until becomes concrete at 1 foot deep.

If you want it to be unaffected for the first foot and then suddenly hit a hard concrete layer, try this:

erode_limit 0.0 1.0 1.0erode_limit 0.9 1.0 1.0erode_limit 1.0 0.0 0.0

Going the other way, if you want a hard layer that gets softer as it breaks through, maybe something like mud that's dried out on the surface, try this:

erode_limit 0.0 0.25 0.25erode_limit 0.25 1.0 1.0

It only tests the depth directly under the wheel. It can go deeper than the limit because the radius will affect neighboring areas that might already be under the limit. Shouldn't get too far though. How deep is it going?

The ground was completely flat, 0.00. It went as deep as 0.75ish. But was too bumpy for me to keep hitting the same line. I'll have to test it more to see if it would have gone deeper. I did have erode set on 50 (going for quick testing ), maybe that could be why, not as accurate?

A big erode setting might make it worse but the real reason is because it checks the spot under the wheel, and then lowers the entire radius. (Obviously, less at the edges but you know what I mean.) So if you dig at one spot to put it under .5, then go 2 feet to the side and go again, it'll put it below the limit if the radius is over 2 feet. Probably would have been nicer to test at each point in the height map but this way was faster and easier.
